The former Big Brother star and her cute-as-a-button daughter were among the famous faces at the Odeon Leicester Square on Sunday, 18 January.
Imogen looked flawless in a sleek outfit of dark skinny jeans, black jumper and faux fur gilet, while little Ariana was dressed in her Sunday best, topped with a cute blue bow.
The tot was also toting around a pink-clad baby doll, which Imogen revealed "she can't go anywhere without… even if she throws her 30 times a day!"
Welsh model Imogen revealed little Ariana, two, can get "overwhelmed" at premieres and loves to run around and take it all in... though she looks good as gold in these pictures!
The mother-daughter outing came shortly after Imogen told The Guardian how much her life has changed after having Ariana.
"If anybody met me now, they'd never think I was the same person who was doing glamour modelling on the covers of men's magazines," she said.
"These days happiness for me is all about being with my two-year old daughter, Ariana. I know it sounds corny but I'm just so delighted to spend every single day with her – it's a kind of love that you think you will never get. I just watch her grow, and think how lucky I am to have her."
Ariana's dad is Imogen's boyfriend Adam Horsley.
